[Amps] ETO Model 70 Amplifier

[Paul Christensen]

Two versions of the original ALPHA SEVENTY were offered.  The 70V is the vapor-cooled version which uses the 3CV1500A7 and the 70A
was the air-cooled version, using a 3CX1000A7.   Both amps offer instant-on capability with the air cooled version offering somewhat
less power and plate dissipation as it's vapor-cooled counterpart.   Both amps were built using very high quality components and
very much resemble the model 77Dx in appearance.  I believe production began in early 1970 and ended in the mid '70s.  You can find
more information at the Alpha legacy amp web page:
